7z无法提取使用ZipFile.CreateFromDirectory打包的.zip文件

Question

I wrote a programm which zips some files together, for the zipping I am using this command:

ZipFile.CreateFromDirectory(My.Settings.UploadTemp, filename)

But the Problem is everytime I try to extract the images with 7z I get an error.

unsupported compression method

But with the standard Windows 7 archive tool everthing works.

EDIT: I found a workaround for my Problem.

Dim zipper As ZipArchive = ZipFile.Open(Path, ZipArchiveMode.Create)
zipper.CreateEntryFromFile(...)

works greate

Answer 1

I tried this and it seems to work. Which version of 7zip are you using? Can you try to install the latest one?
